Hagalund (pronunciation) is a residential area and railway yard in Solna Municipality, 5 km north of central Stockholm. It is known for the blue highrise buildings "Blåkulla" (Blue Hill or Blockula) which, against a rather strong and long-lasting opinion, in the beginning of the 1970s replaced a picturesque working-class and craftsman neighbourhood built in the 1890s and portrayed by artist Olle Olsson Hagalund. There are still about half a dozen old houses preserved, a minor area called Gamla Hagalund (Old Hagalund) in the eastern part of the area.
It has eight large light-blue residential buildings that consist of 13 floors and an extra roof floor. The houses can be seen from Kaknästornet.
Hagalund is close to Solna centrum, about 1 kilometer. It is also near Haga Palace which is in Hagaparken. It is near the new Swedish national stadium Friends Arena. It is not very far away from Karolinska University Hospital.
